Is IFI (Instant File Initialization) compatible with tempdb growth? Recently I needed to increase my tempdb by 40 Gb and it took 15+ minutes to complete. I verified that the user had already been added to Perform Value Maintenance Task and also verified that other user databases took seconds to complete.
I didn't find any documentation or link that would have in-depth IFI details with regard to TempDB. I really appreciate your suggestions.
